Abstract: PURPOSE: An apparatus for remotely controlling a radio frequency(RF) unit in a mobile communication base station transceiver(BTS) system is provided to separate the RF unit from a BTS to install the RF unit in a remote place, and to mount a remote interfacing device between the BTS and the RF unit, so as to remotely perform status controlling and status monitoring relating to an RF processor through an RF cable. CONSTITUTION: If control data for status monitoring and operation controlling of a radio frequency(RF) remote unit(RRU)(50) is transmitted from a base station transceiver(BTS)(30), a controller(41) of a remote interface unit(RIU)(40) receives the control data and transmits the control data to a transmission modem(42). The transmission modem(42) performs a frequency shift keying(FSK) modulation for the control data, and transmits the FSK-modulated data to a demultiplier(43). The demultiplier(43) demultiplies the data as alpha, beta, gamma, respectively, to output the data to the first, the second, and the third diplexer(44,44a,44b). The diplexers(44,44a,44b) separate the control data from frequencies of data received from the RRU(50), and transmit the separated data to each of RRUs(51,52,53), then control state monitoring and operations of the RRUs(51,52,53). Status monitoring results and operation controlling results transmitted from the RRUs(51,52,53) are received in the diplexers(44,44a,44b). The diplexers(44,44a,44b) separate frequencies of the transmission modem(42) from frequencies of receiving modems(45,45a,45b), and transmit data values corresponding to each sector to the receiving modems(45,45a,45b).
